specific Embodiment approach 1

[0047] Such as figure 1 and Figure 5 As shown, the device is composed of a ring top cover (8), a circular bottom plate (9) and 8 spiral separators (6) (the geometric relationship is as follows figure 2 ); the outer diameter of the ring top cover is equal to the diameter of the circular bottom plate, the center of the circle (12) of the ring top cover and the circular bottom plate is coaxial and parallel to the plate surface, and 8 spiral separators (6) are arranged along the ring top cover (8 ) The rings are evenly rotated counterclockwise, the origin of each spiral coincides with the center of the circle, the height is the distance between the top cover and the bottom plate, and the upper and lower sides are connected with the ring top cover and the circular bottom plate; the section of the spiral separator is 2 adjacent The equiangular helical arm, the equal angle is 90°, the total rotation angle is 180° (that is, the golden spiral), the arc length ratio of the inner and ...

specific Embodiment approach 2

[0050] Such as Figure 6 and Figure 7 As shown, in the circular bottom plate (9) in Embodiment 1, a liquid discharge port (29) is added to form a circular bottom plate (25) with a liquid discharge port, and the diameter of the liquid discharge port is less than or equal to the diameter of the air outlet of the circular top cover , and connected to the liquid discharge cylinder (23). When in use, the outlet of the liquid discharge cylinder (24) is not below the liquid surface, which acts as a seal to prevent the leakage of the airflow from interfering with the separation area. After the gas-liquid separation, the liquid drops on the outer wall of the gas-liquid surface channel Converge upwards to form a stream, and the liquid flow is combined to the bottom of the channel and the center of the circular bottom plate under the joint action of gravity and air pressure, and flows out through the liquid discharge cylinder (23). Other implementation details are the same as those in ...

Abstract

A new type of gas-liquid separation device, the airflow enters from the periphery, and is constrained by the spiral separation structure to accelerate the rotation to the center. During the rotation process, the gas-liquid separation is completed, and the separated airflow flows out from the airflow outlet along the center upwards, and the separated liquid is collected from the The outer edge of the bottom or the bottom center discharge port flows out; when the air flow passes through the gas-liquid separation zone in the spiral separation structure, the pressure and speed change continuously, and it is in a state of turbulent flow, and the flow speed continues to accelerate. The resistance is always less than the sum of inertial force and outward pressure, and the liquid droplets are accelerated to the outer wall of the gas-liquid separation area to complete the gas-liquid separation.

Description

technical field [0001] The invention relates to a novel gas-liquid separation device, in particular to the invention of utilizing the Bernoulli effect of a spiral separation structure to realize gas-liquid separation. Background technique [0002] The gas-liquid separation device is a common chemical equipment, which is mostly used in the top of the chemical reactor, the upper part of the boiler or evaporator, and environmental protection equipment to separate the liquid droplets in the gas. At present, the existing gas-liquid separation devices can be divided into six types according to the working principle: gravity sedimentation, inertial separation, cyclone separation, electric separation, filtration, and fiber screen separation. [0003] The gravity sedimentation separation device is provided with an expansion part on the gas flow channel. After the gas flow rate is reduced, the liquid droplets will settle and separate under the action of gravity. The structure of the ...
